[quote=apailthorp]I got it to work, but only after a couple of failed attempts on my new Vista machine. The problem I ran into was that I hadn't yet set the option on Vista File Explorer under "Organize", "Folder and Search Options", "View" (tab), uncheck "Hide extensions for known file types". As a result, I was naming the file "sync.ico.ico", without seeing the final ".ico".

Once I got the file properly named (since with the option unchecked I could see the whole name), everything worked as described.

Thanks!

Thanks for the above. I worked on his for 2 hours before I ran into your post. After I 'unhide' the file extensions, I realized mine was also named 'ico' twice. It's great now!
Again, thanks to all that worked so hard to get this to work
